2. A single screw bulk carrier has an engine delivering 12 000 kW power with a shaft rotation of 90 revolutions per minute. The ship operating speed is 16 knots, and average wake coefficient is and thrust deduction coefficient -0.05. The propeller immersion is 7 m (from water surface to hub). a. Select the appropriate B4-70 propeller, (stating D, P. n. J) b. Using Keller's formula, find if this propeller shall cavitate or not at seawater temperature of 25 °C.
